Answer:
first thing to do is combine like terms
now you would have -x-4=4
this is because you added -6x+5x
now you would add 4 to each side
now you would have-x=8
then you would divide the negative because x has to be positive
now you would have x= -8
that is your answer. if you any questions just ask :D
Step-by-step explanation:
Answer:
63pi
Step-by-step explanation:
the formula for the volume of a cylinder is pi r^2 h
r=radius
h=height
3=r
7=h
pi((3)^2)7
63pi units^3
Hope that helps :)
Step-by-step explanation:
option a is correct
and d too and
-4b⁴ one Is wrong and -5x³
Answer:
4,n=4
Step-by-step explanation:
D=(n,-2) and E=(n,2)
the distance from D to E ,
√{(n-n)^2+(-2-2)^2}=√16=4
the co-ordinate of point C=(0,-2)
given,DC=DE
→√{(n-0)^2+(-2+2)^2}=√16
→n^2=16
therefore,n=4
Answer:
D
Step-by-step explanation:
The arcsine (
) function of x is defined as the inverse sine function of x when -1≤x≤1.
So, when
we have that
This gives us the domain 
of the function 
The range of the function 
is 
so the range of the function 
is the same (options A and C are false).
When x=-4,
So, option B is false and option D is true.
